I'm just happy they waited until the IGTC pack was released to leave Laguna Seca.
Unfortunately since the game is based on licensed series' it's not as open as the first game. You can only select between the 2018 & 2019 BGT seasons or the 2019 IGTC season (as well as whatever other series they may add). However you can edit the length of sessions or just skip practice and qualifying as well as set the race length from anywhere between 5 minutes to 24 hours (you can even do 2 24 hour races if you want to) plus change things like stint length. Custom liveries are also unavailable in Championship mode.
Hopefully this changes at some point so we can do our own custom calendars and use custom liveries.
